NICE-POWER DC Power Supply Variable, 0-400V 0-1A
This bench power supply provides a fixed ceiling of 400V with 1A maximum current. It features four memory storage slots (M1–M4) for quick recall of commonly used voltage/current combinations, reducing setup time between experiments. An encoder knob allows precise voltage and current adjustments, while the lock button protects against accidental re-tuning. A four-digit color display offers high-resolution readings (0.01V, 0.001A) for accurate monitoring. The unit includes an output switch to disconnect the load when needed and a memory-aware design suitable for repeatable high-voltage testing.
YHYWJHY 2000W Adjustable DC Switching Power Supply
With a high power rating of 2000W, this supply covers a wide range from 24V to 600V. It is suitable for demanding applications that require significant headroom and quick voltage adjustments. The device uses a high-precision 4-digit LED display to monitor voltage and current, making it easier to set exact targets for sensitive experiments. While primarily a high-voltage unit, its broad range supports testing of components, cables, and circuitry that operate around the 400V mark, all with robust display and control visibility.
NICE-POWER DC Power Supply Variable, 0-600V 0-1A
This programmable DC power supply supports PC connectivity via RS-232/USB, enabling computer-based control for voltage/current programming, data export, and graphing. It preserves four memory values and includes the same encoder knob and lock button features for precise operation and safety. The optional PC software facilitates automated test sequences, ideal for labs and development environments needing reproducible high-voltage tests in the 0–600V range.
NICE-POWER DC Power Supply Variable, 0-800V 0-1A
This model extends voltage capability to 0–800V with 1A maximum current. It offers extensive control via RS-232/USB and optional Windows software, making it suitable for automation and laboratory data logging. It includes four memory slots for quick recall, an encoder knob for fine adjustments, and a safety lock feature to prevent accidental changes. The large display provides clear HV measurements, aiding safety-conscious operation during high-voltage experiments.
NICE-POWER DC Power Supply Variable, 0-300V 1A
This compact unit provides a safe and compact option for projects requiring up to 300V at 1A. It features a precise encoder knob for voltage and current setting, a memory storage function to save frequently used values, and a robust display that makes it easy to monitor during high-voltage tests. A cooling fan helps maintain performance during extended operation, and the load protection features reduce risk to connected devices.
Buying Guide
- Voltage range and headroom: If you work near 400V or need flexibility beyond it, consider models up to 600V or 800V to accommodate future projects.
- Current rating: Ensure the current limit matches your load. Higher voltage supplies with low current can be safer for delicate components, while higher current supports bulk testing.
- Control interface: Encoder knobs provide quick manual tuning; RS-232/USB and PC software enable automation, data logging, and reproducible experiments.
- Memory storage: Multi-slot memory (M1–M4) enables fast recall of common settings, minimizing misconfiguration during experiments.
- Safety features: Output switches, lock buttons, and over-current/short-circuit protection help safeguard both the power supply and the device under test.
- Display clarity: Four-digit, color LCDs with voltage/current resolution (0.01V / 0.001A) aid precise adjustments and monitoring.
- Software compatibility: Windows-only software may limit environments; verify OS compatibility or look for hardware with simpler USB control if cross-platform work is needed.
- Size and cooling: High-power models often require adequate ventilation; consider form factor and cooling behavior for bench use.
- Safety certifications: Check for relevant safety and compliance marks to ensure reliability in educational or professional settings.
- Future-proofing: If your projects may scale to higher voltages, select models with 0–600V or 0–800V ranges to avoid early replacement.
